Nobody was injured when a northbound Caltrain struck a car on the tracks at 16th Street in San Francisco Sunday evening, according to a Caltrain spokeswoman.

Train 439 struck the car around 5:32 p.m., according to spokeswoman Christine Dunn.

Nobody was inside the car when it was struck, Dunn said.

The accident briefly shut down service, but trains were moving in both directions on the southbound tracks. Caltrain later opened the northbound track and resumed full service. Because Caltrain operates only hourly service on Sunday, delays were minimal, Dunn said.
